Also, is there a benefit to constructing a gigantic CSP array or many smaller arrays? If an array small enough to be handheld can create enough heat to burn through metal, then surely it would also be enough to drive a steam turbine on a smaller scale.

@Angilion: of course the problems here are the same problems we have with solar panels, especially when considering the amount of land mass required to generate the vast quantities of electricity we would need to supplant carbon based fuels. At most (or until we figure out a way to put a large number of solar arrays into space and transmit the power back to earth), this kind of technology can only be ancillary to other, more reliable, sources of power.

I was not aware that that CSP arrays were already in use to generate electricity. Due to the quantity of energy generated, however, it looks to me that CSP arrays make far more efficient use of solar energy than do solar panels (i.e. a CSP array-driven steam turbine would generate more electricity than a solar panel). I am no scientist however, nor to I have the inclination to research this on the Interweb, so feel free to dispute this with data.

"So Mythbusters failed to do it (multiple times) with the help of a lot of money, two extremely ingenious minds, an entire college, multiple engineering and science geeks, and PRESIDENT OBAMA. But this teenager did it with a bunch of mirrors, a little wagon, and a shed of doom. "

Anyone can do it this way. The Mythbusters were trying to do it with people, and that's why it failed.

Why don't you stand in front of it?
We can find out what focused sunlight does to troll flesh. Do you turn to stone like in David the Gnome?

@SilverThread

This isn't even close to the concept of a laser. Please know what you're talking about before giving snarky remarks.
But I guess this is the stuff that makes comment boards go 'round, isn't it?

They've been using this same concept for a solar generator in AZ for decades now.

I have a material so dense this would not get through.... let us us put a Democrat in front of this, then you will see what cannot be beaten.

its not a laser since there is no stimulated emission.

@Angilion Could they use a giant Swiffer Duster of some kind instead of water to clean them?

wonder how much gas he used on that piece of wood to get it to light.

Oh, and a death ray that reaches all of 16in (~40cm to you Euro's), color me unimpressed.

>>another thing, just a little bit of dust (which is rather common in the desert, eh?) drops the efficiency of a solar array a LOT! Cleaning all those arrays would take TONS of water every week, which is not a good idea (cost wise) in the desert.


Yes, dust has been found to be a problem. There are automated systems that combine water and brushes and those use *much* less water. Work is being done on waterless cleaning systems and on bringing down the cost of systems developed by NASA for surface probes in very dusty environments. They work, but the cost of fitting a large scale CSP mirror array with them is impractical.

Thinking of water, though, CSP does have a massive bonus for deserts near enough to the coast - it can used to desalinate and purify huge amounts of seawater as a side-effect of how it works, without greatly reducing efficiency of electricity production.

@shizzamX, some fireflys got into the shed, of course!

@Angilion, your calculations are similar to something I read, of how many tousands of square miles of solar arrays it would take.
